<P>PROBLEM TO BE SOLVED: To provide a route guidance device capable of setting an appropriate guide route where a deviation hardly occurs. <P>SOLUTION: A car navigation 100 sets a guide route from a departure place to a destination and performs route guidance from the departure place to the destination, based on the guide route. The controller 10 of the car navigation 100 searches the guide route from the departure place to the destination (S20), searches whether a traffic intersection and a road being the same as or similar to a traffic intersection and a road of deviation road information stored in a storage device 60 exist or not in the searched guide route (S21), and re-searches the guide route by reducing a priority in adopting a road as the guide route compared with a case before detecting a deviation, with respect to an exit road indicated by the deviation road information extracted in the search (S23). <P>COPYRIGHT: (C)2012,JPO&INPIT |
